Abstract
A multiple block lifting device that includes two support arms pivotally connected at the opposite ends enabling the support arms to move from a closed, parallel configuration to an open, linear configuration. Attached to each arm is at least one block attachment unit that selectively connects to one block. In the preferred embodiment, the movement of the support arms and each block attachment unit is controlled by hydraulic cylinders and a main control valve. When paired blocks are aligned on a pallet, the device is in a closed, parallel configuration, and each block lifting unit engages a block. The device is then lifted and the support arms are aligned in the open, linear configuration. Each arm may include an optional extension arm that enables the device to lift additional blocks.
